1. Field of the Invention
The present invention relates in general to an image layout method, and more particularly, to a layout method image quality.
2. Description of the Related Art
The earliest dynamic image visible to human beings was the documentary movie. With the invention of the cathode ray tube (CRT), commercial television has become a necessary home appliance. The development of science and technology has further extended the application of the cathode ray tube into the desktop monitor of the computer industry for the last several decades. However, as various kinds of cathode ray tubes suffer from radiation problems, and the internal electron gun occupies such a large volume, the cathode ray tube has become inapplicable for thin and light products.
The above problems thus initiated the development of flat panel display, such as the liquid crystal display (LCD), field emission display (FED), organic light emitting diode (OLED), and plasma display panel (PDP). Among the above displays, the development of the liquid crystal display is most significant. The liquid crystal display possesses the characteristics of thinness, smallness, lightness and applicability of small, medium and large area display, and has been applied to the portable wireless communication and network techniques.
The image layout method is a key feature determining the quality of the image displayed by the liquid crystal display. Referring to
In another image layout as shown in /n for n image input lines.
As shown in and 2 Ã
. Consequently the nth image input line has (n−1)Ã
m cross overlaps. With such a conventional layout, the number of cross overlaps for each image input line is different, causing different load and overlap capacitance. Therefore, the application specific integrated circuit requires a different driving power to drive each image input line. Further, between two consecutive front and rear sections, the nth data line of the front section is connected to the first image input line, while the first data line of the rear section is connected to the nth image input line. As the number of cross overlaps between the connected data lines and the image input lines varies too much, the images displayed by two neighboring sections contain a gap, seriously affecting the image quality.
The present invention provides a layout method for improving image quality. The present invention is characterized in locating the image input line connected to the last data line in a front section in a proximity of the image input line connected to the first data line in the neighboring rear section. Therefore, the load difference between the neighboring sections is reduced, such that the uniformity of the image is improved.
The layout method provided by the present invention comprises the following steps. The layout method is applicable for a display that comprises a plurality of pixels and a plurality of control circuits. The pixels and control circuits are divided into a plurality of sections.
The data lines in each section are connected to the image input lines. The layout method is characterized by locating the image input line connected to the last data of the front section in proximity of the image input line connected to the first data line in the following section.
In one embodiment of the present invention, other image input lines are neighboring to the image input line.
Preferably, the number of the data lines is the same as the number of the image input lines.
Further, the number of the sections is determined according to the number of the pixels and the number of the image input lines.
In one embodiment of the present invention, the image input lines are connected to the application specific integrated circuit.
The display includes a liquid crystal display such as a low-temperature polysilicon thin-film transistor liquid crystal display or non-amorphous thin-film transistor liquid crystal display.
The present invention further provides a layout method for improving image quality suitable for use in a display comprising a plurality of pixels and control circuits. In the layout method, the pixels and the control circuits are divided into a plurality of sections. Each section includes a plurality of data lines. Each data line is connected to a corresponding image input line. Between two neighboring sections, when the first image input line is connected to the last data line of the front section, the first data line of the rear section is connected the second image input line proximate to the first image input line.
In this embodiment, the second image line is neighboring to the first image input line.
According to the above, the present invention is characterized in locating another image input line connected to the first data line of the rear section in proximity of the image input line connected to the last data line of the front section. Therefore, the load difference between the neighboring image input lines is reduced, such that the image uniformity is improved.
The above objects and advantages of the present invention will be become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings.
The layout illustrated in
Similarly, the second section 404 comprises second pixels 412, second control circuits 414 and n data lines 416. For a quarter common intermediate format, when there are n image input lines, the number of the sections is 176 Ã/n . Therefore, the number of sections is determined according to the numbers of pixels and image input lines.
Each of the data lines of the first and second sections 402 and 404 is connected to the corresponding image input line. Between the first section 402 and the second section 404, if the nth data line of the first section 402 is connected to one of the n image input lines, the first data line of the second section 404 is connected to another image data line in proximity of the image data line. Preferably, this other image data line is neighboring to the one image data line to obtain a better image quality. In this embodiment, the nth data line of the first section 402 is connected to the second image input line, while the first data line of the second section 404 is connected to the first image input line neighboring to the second image input line. Therefore, the number of cross overlap of the n data lines in the first section 402 and the second image input line is (n−2)Ã, which has the least difference from the number of cross overlaps (n−1)Ã
of the first data line of the second section 404 and the first image input line. Therefore, the gap of the images displayed by neighboring sections to improve image quality. It is appreciated that, other than the specific layout for the nth data line of the first section 402 and the first data line of the second section 404, layout for other data lines can be implemented by various methods as long as the corresponding image input lines are connected.
Each of the data lines of two consecutive neighboring mth and (m+1)th sections 502 and 504 is sequentially connected to the corresponding image input lines. Between two consecutive neighboring mth section 502 and the (m+1)th section 504, if the nth (i.e. the last) data line of the front section 502 is connected to one of the n image input lines, the first data line of the (m+1)th rear section 504 is connected to a image input line in proximity of the image input line which is connected to the nth data line of the front section 502. Preferably, this other image data line is neighboring to the one image data line to obtain a better image quality. In this embodiment, the nth data line of the mth section 502 is connected to the nth image input line, while the first data line of the (m+1)th section 504 is connected to the (n−1)th image input line neighboring to the nth image input line. Therefore, the number of cross overlaps of the nth data lines in the mth section 502 and the (n−1)th image input line is 0, which has the least difference from the number of cross overlap 2 of the mth data line of the (m+1) (th section 504 and the mth image input line. Therefore, the gap of the images displayed by neighboring sections improves image quality. It is appreciated that, other than the specific layout for the nth data line of the mth section 502 and the first data line of the (m+1)th section 504, layout for other data lines can be implemented by various methods as long as the corresponding image input lines are connected.
Each of the data lines of the mth and (m−1)th sections 502 and 504 is connected to the corresponding one among the n image input lines. Between the mth section 502 and the (m+1)th section 504, if the nth data line of the first section 502 is connected to one of the n image input lines, the first data line of the (m+1)th section 504 is connected to another image data line in proximity of the one image data line. Preferably, this other image data line is neighboring to the one image data line to obtain a better image quality. In this embodiment, the nth data line of the mth section 502 is connected to the nth image input line, while the first data line of the (m+1)th section 504 is connected to the (n−1)th image input line neighboring to the nth image input line. Therefore, the number of cross overlaps of the nth data lines in the mth section 502 and the (n−1)th image input line is 0, which has the least difference from the number of cross overlap 2 of the mth data line of the (m−1)th section 504 and the mth image input line. Therefore, the gap of the images displayed by neighboring sections improves image quality. It is appreciated that, other than the specific layout for the nth data line of the mth section 502 and the first data line of the (m+1)th section 504, layout for other data lines can be implemented by various methods as long as the corresponding image input lines are connected.
According to the above, the present invention is characterized in locating one image input line connected to the last data line of the front section in proximity of another image input line connected to the first data line of the rear section neighboring to the front section, such that the load difference between neighboring image input lines is minimized, and the image uniformity is improved.
While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
